CAR-WHEEL.

SPECIFICATION forming part of Letters Patent No. 366,181, dated July 5,1887.

Application filcdNovrmher 1, 1886. Serial No. 217,734. (No model.)

To all whom it may concern:

Be it known that I, EDGAR PECKHAM, of Syracuse, in the county of. Onondaga, in the State of New York, have invented new and 5 useful Improvements in Oar-\Vhecls, of which the following, taken in connection with the accompanying drawings, is afull, clear, and exact description.

This invention consists in a novel construction of a car-wheel, combiningsimplicity with durability and sufficient elasticity to obviate undue jarring of the wheel.

The invention is fully illustrated in the an nexed drawings, wherein Figures 1 and 2 are respectively outer and inner side elevations of a car-wheel embodying my improvements. Fig. 3 is a transverse section of the same. Fig. 4. is a detached transverse section of onehalf of the web, with its re-enforcing rings; i and Fig. 5 is a detached face view of a portion of the sectional retaining-ring, by which the web is locked on the tire.

Similar letters of reference indicate corresponding parts.

A represents the caraxle, B the hub of the wheel, G the web, and D the tire. The said hub I prefer to form either of cast-iron or caststee], and with a circumferential flange, a, and a circumferential rabbet, r, at one side of said flange. The web G, I form of a single disk or plate of wrought-steel, and with a central eye, by which it is seated in the rabbet 1- of the hub. By means ,of an annular collar, I), slipped onto the rabbeted portion of the hub, and bolts a, passing through the said collar I), web 0, and flange a, the web is clamped between the collar and flange.

In order to brace the web (J, I dish the same around its central portion and conform the adjacent sides of the flange a and collar I) to the disk of the web, as shown in Fig. 3 of the drawings. The outer peripheral portion of the web I rc-enforce by annular plates or rings d and c, riveted to opposite sides of the aforesaid portion of the web.

The tire D may besecured to thedescribed web in any suitable and well-known manner, and I wish it to be distinctly understood that ring 6 and entering an undercut groove, i, in

the inner circumference of the tire, the outer retainingring, It, being provided with an outward flange, which enters the undercut portion of the groove 2', as shown in Fig. 3 of the drawings. Bolts Zlpass through the plates d, e, h, and h, and interveningweb (l, and are provided with nuts, by which the said parts are securely clamped together.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A car-wheel having a web composed of a single wrought-metal disk, re-cnforced atits periphery by rings extending around the peripheral portion of said disk and secured thereto, substantially as set forth and shown.

2. A ear-wheel composed of a hub, a sin gle annular wrought-metal disk forming the web, re-enforcing rings attached to the peripheral portion of said web, and a tire secured to said web, substantially as specified.

3. In a carwheel, the combination of a single wrought-metal plate, dished around the center and constituting the web of the wheel, and a hub having a flange and a collar, holding between them the central portion of the aforesaid plate and having their inner sides conformed to the dish of said plate to brace the same, substantially in the manner specified and shown.

In testimony whereof Ihavehereunto signed
